Axillary lymph nodes
Axillary Lymph Nodes
The Axillary Lymph Nodes (pronunciation: ax·il·lar·y lymph nodes) are a group of lymph nodes located in the axilla (armpit), which play a vital role in the lymphatic system of the human body.
Etymology
The term "Axillary" is derived from the Latin word "Axilla" meaning armpit, and "Lymph Nodes" is derived from the Latin "Lympha" meaning water, referring to the lymph fluid that they filter.
Function
The primary function of the Axillary Lymph Nodes is to filter lymph - a clear or white fluid that is part of the body's immune system. These nodes act as a filter for harmful substances and contain immune cells that can help fight infection by attacking and destroying germs carried in through the lymph fluid.
Anatomy
The Axillary Lymph Nodes are divided into several groups including the pectoral (anterior), subscapular (posterior), lateral, and central nodes. Each group is named based on their location in the axilla.
Clinical Significance
The Axillary Lymph Nodes are often checked in the diagnosis and staging of breast cancer. They can be examined by a physical examination or imaging studies, or by biopsy where a sample of tissue is removed for laboratory testing.
